310 Watt LED UFO High Bay | 45000 Lumens | 5000K | 277-480V

Product Overview

This is a 310 Watt LED UFO High Bay designed for commercial and industrial spaces requiring high-output overhead lighting. It delivers 45,000 lumens at a 5000K color temperature, providing a daylight-white output suitable for large, open areas.

The fixture is built with a die-cast aluminum housing and a polycarbonate lens. It operates on 277-480V input and supports 0-10V dimming. The standard beam angle is 120 degrees for broad coverage.

It is rated for 50,000 hours (L70) and includes a 4kV surge protector. The fixture is finished in black and weighs 13 pounds.

Mounting options include hook (standard), with pendant and surface mounting available. The fixture comes with a 5-foot power cord and an 8-inch dimming cord.

Where This Product Fits Best

This LED UFO High Bay is suited for warehouses, manufacturing plants, distribution centers, and similar facilities with high ceilings and large open floor plans.

It is intended to replace 1000 to 1500 watt metal halide fixtures, making it appropriate for retrofit or new construction where high lumen output is required.

The fixture's 277-480V compatibility supports use in facilities with higher voltage electrical systems. The 5000K color temperature is suitable for environments where clear, bright visibility is needed.

IP65 and IK10 ratings allow installation in locations exposed to dust, moisture, and areas where impact resistance is necessary.

Performance and Functional Considerations

The fixture outputs 45,000 lumens at 145 lumens per watt, providing high efficiency for large-area illumination. The 120-degree beam angle supports wide, even light distribution.

0-10V dimming allows for integration with compatible dimming controls, enabling adjustment of light levels as needed. The fixture maintains a power factor of 0.90 and a maximum THD of 20%.

The polycarbonate lens is designed for durability and consistent light output. The fixture operates reliably in temperatures from -40°F to 113°F.

Surge protection up to 4kV is included for electrical reliability in demanding environments.

Installation and Long-Term Use

The fixture is designed for overhead mounting using the included hook. Pendant and surface mounting options are also supported if required by site conditions.

The 5-foot power cord and 8-inch dimming cord provide flexibility for connection during installation. The fixture's weight and dimensions should be considered when planning mounting points and support structures.

With an L70 lifespan of 50,000 hours, the fixture is intended for long-term use with minimal maintenance. The die-cast aluminum housing and polycarbonate lens support durability in industrial settings.

IP65 and IK10 ratings ensure the fixture can be installed in areas exposed to dust, water jets, and physical impacts without compromising function.

How This Fixture Is Commonly Used

After installation, this UFO High Bay provides consistent, high-output lighting for large spaces. The 0-10V dimming feature allows you to adjust light levels to match operational needs or energy management protocols.

The fixture's 5000K color temperature supports tasks requiring clear visibility and accurate color rendering. The wide beam angle reduces shadowing and helps maintain uniform illumination across open areas.
